Witnesses told how the £5.7million Phenom 300 aircraft was trying to land at the airport when it smashed through the perimeter fence before exploding.

The jet smashed into cars on the British Car Auctions site, sparking a huge blaze which destroyed many vehicles, but no one on the ground was hurt.

Footage taken in the aftermath of the explosion showed the plane was severely broken up shortly after impact among the dozens of severely damaged cars.

Saudi ambassador to the UK, Prince Mohammed bin Nawaf Al Saud, today offered his condolences to the large and wealthy Bin Laden family, who own a major construction company in Saudi Arabia.

The statement, translated by the BBC, said: "His Royal Highness Prince Mohammed bin Nawaf Al Saud ... has paid his condolences to the family and relatives of Mohammed bin Laden at Blackbushe Airport in Britain for the great loss they have suffered as a result of the crash of the plane that was carrying the family."

A further statement said the embassy would work with the British authorities to ensure a quick repatriation of the bodies for burial.

Acting Chief Inspector Olga Venner, of Hampshire Police, said: "We can confirm that there were four people on board, including the pilot.

"Sadly there were no survivors. No-one on the ground has been injured and we would urge anyone with any information, including pictures or videos, to contact 101."

Although based in Saudi Arabia, the aircraft was flying into Hampshire from Milan. The Bin Ladens have interests in northern Italy.

Retired Daphne Knowles said she had seen the twin-engined jet flying very fast towards Blackbushe aerodrome near Farnborough, Hants.

The 70-year-old former MoD research assistant added: “It was flying with its engine screaming and very fast. I knew straight away something wasn’t right.

“I saw it at about 2,000ft and remember thinking the pilot couldn’t be landing as it was going too fast.

“It just dived down towards Blackbushe and the next thing I saw was a huge column of thick black smoke. At first I thought it was a fighter jet because of the loud noise it was making and its high speed.”

Joe Ramos was working at the BCA ­warehouse when he heard a “loud bang”.

He said: “We went out to see a private jet had gone over the airport fence.

“It clipped the fence, spun around and crashed into the cars where they are sold. The fire started at the front of the plane, worked its way to the back and spread outwards on to the parked cars. The whole place was engulfed with very thick black smoke.”

Andrew Thomas was paying for a car when the plane came down. He said: “It nose-dived into the cars and exploded on impact.”

Aviation fan Robert Belcher was driving home at the time of the crash.

He said: “I could see the plume of smoke from about five miles away and was hoping it was just a car fire rather than an aircraft accident.

“Apparently the aircraft was landing and just didn’t stop. Locals said it was ­registered in Saudi Arabia. It’s been a regular visitor to the airport for a few months.”

In a statement, an airport spokesman said: "Blackbushe Airport confirmed that a Phenom 300 jet with four persons on board crashed near the end of the runway around 3.09pm while attempting to make a landing.

"The scene was attended by Blackbushe Fire and Rescue within minutes, followed by Hampshire fire, police and ambulance units. Emergency services are currently controlling the scene."

Described as “truly ­revolutionary”, 73 Phenom 300 were sold in 2014, making it the most delivered business jet in the world for the second year running, according to the General Aviation ­Manufacturers Association.

The Aviation Safety Network said this is the first fatal crash involving the jet.

It was revealed earlier that the aircraft was owned by Salem Aviation of Jeddah, a part of the Bin Laden Group.

The plane’s registration, HZ-IBN, is the exact same registration used by Osama bin Laden’s father, Mohammed.

Mohammed bin Laden died when he crashed his Beechcraft 18 twin propellor plane into a mountain landing strip in Usran, Saudi Arabia in 1967.

The company is named after Osama’s eldest brother, a keen amateur pilot.

Salem bin Laden died in San Antonio, USA in 1988 when he crashed his light aircraft into high voltage power lines.

The ultralight aircraft fell 115ft to the ground. Salem died of head injuries due to the fall.
